OILES 81 Poliolefin resin bearing containing lubricating oil

CUSTOMIZED PRODUCT

Poliolefin resin bearing with less stick slip and high performance under abrasive circumstance.
OILES 81 is a self-lubricating bearing composed of polyolefin resin with oil and special fillers evenly. Various grades are available. Features Usable without lubrication Low friction coefficient and remarkable impact load carrying capacity Retainable of stable performance with excellent wear resistance even under abrasive circumstances where foreign matters are encountered, the mating material is forming rust, or the surface of mating material is rough Injection molding enables complex shape. Suitable for mass production
